Yamaha MT-09 (2014-2021) — Maintenance Specs

The MT-09 (FZ-09 in the US until 2016) houses Yamaha's 847 cc CP3 triple - the engine that defined the modern hyper-naked class in 2014. The 2017 update brought ride modes, better suspension and an LED headlight, but the 2015 and 2019 owner's manuals used here show identical service data: 2.70 L of oil with the filter, 1.93 L of coolant, NGK CPR9EA9 plugs and DOT 4 brake fluid. A quirk worth flagging: Yamaha's manual lists chain slack at just 5.0-15.0 mm, far tighter than typical, and owners should cross-check the swingarm sticker. The same maintenance grid as the MT-07 applies - oil every 4,000 miles, plugs at 12,000, valves at 42,000 km.
